s'rAMP-ArrrXInG MACH-Inn Application. filed April 5,

yelope prior to, afliXing- 'a, stamp thereto.

In a more detailed, aspect, the invention contemplates utilizing, aneflicient, pract cable, and; durable mechanism within the water compartment cooperating with theactuating. plunger in such a Way as to lend to theparts long- Wearing qualities and to make it difficult for the mechanism to, get. out of order, or cooperate improperly.

Anotherobject of; the invention is to: provide compact mechanism that permits quick and easy adjustment of the. Water. ejectorso as to, vary theamount of water discharged on to an envelope.

To these and other endsgtheinvention consists in the construction, and arrangement of parts. that Willappear clearly from the following description when read in conjunction with the accompanying drawings, the novel features being pointed out inthe claims following the dcscriptieng j r In the drawings 2;

vhile 2 is the operating plunger for operatmg the conventional stamp feeding and sev-v ering devicesas, it travels de vnyvardly,3,being the operating handle onthe plunger, and 4 the foot that affixesthe stz'nnp;upon theisurface of an, envelope. v

Suitably attached, to the plunger 2, as for instance by-Ineans of; a" plate 5,,isa vrack- .6 engaging a pinion 7 that is mounted' on an arbor 8 suitably journalled, in, a- Wall of the water compartment 10, The arbor 8 carries a pin 11, theseparts constituting the actuatingmeans, for the ater ejecting mechanism now, to be, described, and hile the rack: and pinion operating means has been found quitev efiicientfor the purposes of "the invention, it is to. be. understood, that other forms of mechanism maybe substituted for the rack, pinion and rotary arbor-just described to ;'effect the necessary-movementof the Water ejecting mechanism.

The. Water compartment includes ope ling 12 in thewall 9, as usual in. this typeof construction, and the water ejector comprises ,a Wide lower portion 13, having the, upturned end; la forvholding a pad 15 anda reduced upper portion 16 having earsferpivotally engaging a post 17 that isfixedly mounted. on

a base 181 carried, by the WallflQ. ],he Water ejector 13is held, in, its; normal, position. as illustrated in Figures 1 and 6 means of a suitable spring coiled-around the post 17 having its free ends, 19 in engagement With the wall 9. and its portions 20 engaging the edges 21 of thelower portion-1301i the Water e ector and thereby moving the latter toward the openings 12. i d

The ater ejector is operated bythe. aforementioned pin 11 through a contact member V that is movablymounted with relation to Figure 5 is a sile, elevation of-the same the Water ejector so astomovethelatter when travelling in one direction and tobe movable independently of the ater ejector When the pin 11 is-travell-ingwin the, direction induced by the upward movement of therackfi. The construction and arrangement of this contact member will now be described.

The contact membercomprises a suitable plate 2.5 having earsor side Walls 26 which are also, p votedion the aforementioned post Referring more particularly to the drawer 17.; Permanentlyattached to. the plate 25 is a support =27ahaving a cam portion 28 at its o tere an a h e' cl d open ng am 1' ceives the threadedadjustin pin 30, I which the,Wa,ter.ejector as, s iown inFigure 5. The plate 25 has its lower end bent upon itself to receive and hold a pin 31 which forms a support for a spring 82, one end of which is designated at 33 and engages the lower part of the water ejector while the opposite end 34 engages a slot in the adjusting pin 30, thus serving to hold said pin in adjusted position.

ment with cam 28 upon further downward movement of the rack 6, the contact member and water ejector are released and the spring portions 19 and 20 throw the water ejector quickly to normal position and I cause the proper amount of water to be discharged through the openings 12. The amount of water thus discharged can be varied by adj ustment of the'pin 30 which permits the cam 28 to be positioned closer to or farther away from the water ejector, and in this manner causing the water ejector to be moved to a greater or less degree as it is opened by the pin 11 through cam 28. 2

Upon the return or upward travel of the rack 6 as the plunger is restored to normal position, pin 11 engages the rear side of cam 28, having reference to Figure 4, causing the contact member to rock on its axis away from the water ejector, as in Figure 6, against the action of spring 32, and without any movement of the water ejector. As soon as the pin 11 passes out of engagement with the cam 28, the contact member is restored to initial position by the spring 82 and the parts are then in readiness for another operation.

IVhile the invention has been described with reference to certain structural details, itis not limited to the precise form or arrangement herein disclosed, andthis application is intended to cover such modifications or changes as may come within the lntent of the improvement or the scope of the following claims.
